You'll wonder where the yellow went


This vintage TV commercial for Pepsodent is something of a classic and almost everyone over a certain age still has the jingle embedded in their brain. The toothpaste is still around apparently.

Wikipedia coyly refers to Pepsodent's miracle ingredient Irium as another word for sodium lauryl sulfate an inexpensive ionic surfactant. It is in fact an inexpensive anionic surfactant - cheap detergent in other words.

Cheap detergent - I shall look at my toothpaste through new eyes from now on.

It's a very common ingredient even today.

At the time I recall there was a rugby club version of this one. To avoid your blog being taken down I will leave it to your imagination.

Demetrius - I believe there was, but as you say, not for publication.
